IMPROVEMENT IN MACHINES FOR IVIINCl-NG MEAT.

Specification forming part of Letters Patent No. 13,990, dated December25, 1855.

To all whom it may concern:

Be it known that I, ALEXANDER LIGHT- HEIsEE, of the city of Reading,inthe county of Berks and State of Pennsylvania, have invented a new anduseful Improvement on the Machine for Mincing Meat; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figurelis a front elevation of the machine closed. Fig..2 is a front view withthe lid or upper half of the machine thrown open, showing thecylinderand knives; Fig. 3, an end section on the line A B, the lettersof reference corresponding.

Fig. l, A B is the upper and lower half of the boX or casing. The upperhalf contains the hopper C. X is the feed-opening and R thedischarge-opening.

L L, Fig. 2, are two pieces of hard Wood ruiming the entire length ofthe inside of the boX, to which they are fastened. Said pieces are forthe purpose of holding the stationary knives I I.

K K K Kare the revolving knives, and are fastened into the pieces E E EE. 'These knives are fastened diagonally into the pieces E E E E, andwhich pieces are fastened to the v square center piece Dby means of thetriangular pieces F F F F, secured to the center -piece D by means ofthe screws G G G G.

The cutting-edge of the knives K K K K is the segment of a circle, andtheir position on the cylinder is a double spiral.

S S are the journals of the cylinder.

IV W are wiper-pieces for the purpose cf wiping the Ininced meat throughthe discharge-opening R.

O O O are a series of spikes on the cylinder for the purpose ofreceiving and pressing into the knives K K K K I I I I the Ineat fedfrom the hopper C through the feed-opening X.

H is the crank-handle for operating the Inachine. By turning the handlein the direction of the arrow it will be observed that the revolvingknives K K K K pass between the stationary knives I I I I, cutting themeat carried forward by the spikes O O O O.

I am aware that Inachines have been constructed in which the cuttingaction was or is produced by means of spikes on a solid cyl- V Inderoperating against stationary knives. In

such machines the cutting is very imperfect, from the fact that thespikes have no cutting action and carry the Ineat full onto thestationary knives, not giving it the sliding motion or the advantage ofthe segment-cutters
